Will a throttle controller void my Roar 4x4 warranty?

No. The Roar 4X4 Throttle Controller is a plug-and-play device that does not modify your ECU, engine mapping, or any permanent wiring. It can be removed in under 2 minutes, returning your vehicle to 100% factory settings with no trace of installation.

How do I install the throttle controller on my Toyota LandCruiser 100 Series V8 (Plug 831)?

Installation takes 10-15 minutes with no tools required. Locate the electronic throttle pedal connector in the driver's footwell, disconnect the factory plug, connect the Roar controller inline between the pedal and factory harness, mount the display unit on your dashboard, and start your vehicle.

Does a throttle controller increase horsepower?

The throttle controller adjusts how quickly your vehicle's existing power is delivered. It does not increase horsepower or torque. It remaps the throttle signal so you feel the power sooner, eliminating the factory-programmed delay between pressing the pedal and the vehicle responding.

Can I use the throttle controller while towing?

Absolutely. Many owners use Sport or Race mode while towing to get better throttle response when merging, overtaking, or climbing hills. Economy mode is great for long-distance touring to reduce fuel consumption.

Is it compatible with aftermarket ECU tunes or performance chips?

Yes. The Roar throttle controller works independently of ECU tunes, performance chips, or exhaust modifications. It complements these upgrades by giving you finer control over throttle delivery.
